We’ve covered both material and cupertino based widgets. Sometimes, we might want to show a widget based on the platform. Flutter offers us a way to manually check for the platform our app is running on. We can then use this information and adapt our designs based on the underlying platform.

import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';

class PlatformSpinner extends StatelessWidget {
  const PlatformSpinner({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    final isIOS = Theme.of(context).platform == TargetPlatform.iOS;
    return Center(
      child: isIOS
          ? const CupertinoActivityIndicator()
          : const CircularProgressIndicator(),
    );
  }
}
...
return Center(child: PlatformSpinner());
...
// Remove the isIOS boolean member
...
  @override
  Widget build(BuildContext context) {
    bool isIOS = Theme.of(context).platform == TargetPlatform.iOS;
    if (isIOS) {
...
